Fodor's Expert Review La Silla Observatory

Administered by the 15-member European Southern Observatory (ESO), La Silla Observatory is one of the largest and most important observatories in the Southern Hemisphere. Free tours are available of the three principal telescopes each Saturday at 2 pm, except during July and August, due to the risk of snowstorms in this period. Note that bookings are accepted only if made via the online visitor form.
